  • Abstract
  • Look Inside

 Eosinophilic granuloma is thought to originate in the reticuloendothelial system and cannot clearly be distinguished from the surrounding tissue during operation.

 An eosinophilic granuloma in the parotid area was removed after 25 days of irradiation at a dosage of 10.0 Gy per 3 days. A thin capsule of connective tissue was observed after the tumor was cut in half. Then, histopathological studies were performed onthis connective tissue to determine the effect of the irradiation.

 Histopathologically, at the periphery of the tissue, atrophy of lymphocytes and destruction of the lymphoid tissue, which were thought to result in anincrease in the connective tissue, were observed.

 It was concluded that a small dose of pre-operative radiation on eosinophilic granuloma in the parotid area made the tumor small and produced a capsule around the tumor.
